Depends but the ones we have at our gym are 17 lbs, 16.5 lbs, and 15 lbs. I put them on the scale to check them... at for the shrug bar, is that the one with the diamond shape to it? or a straight bar. on the straight bar, they can be 45, 50, or 60 lbs.

i had always thought the standard EZ bar weighed 15 for the lighter ones around, and 30 for the heavier steel. i guess ive been telling people wrong info. (ha) gonna go weigh those suckers before any other people ask me away quesitons to which im not 100% sure of. (ps i still think im right however) Sage
